The average temperature on the surface of the Earth is.
A
35*c
B
25*c
C
20*c
D
15*c
Explanation: 

Detailed explanation-1: -The average temperature of the Earth’s surface is presently 15∘C. This is due to the presence of greenhouse gases like CO2 in the atmosphere, which traps heat and keep the temperature higher.

Detailed explanation-2: -"These gases–water vapor (H2O), carbon dioxide (CO2), and methane (CH4)–keep ground temperatures at a global average of about 15 degrees C (60 degrees F)."

Detailed explanation-3: -This process, the greenhouse effect, leads to a mean surface temperature that is 33 °C greater than it would be in its absence. If it were not for the greenhouse gas effect, Earth’s average temperature would be a chilly-18 °C.

Detailed explanation-4: -Greenhouse gases let the sun’s light shine onto Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable.

Detailed explanation-5: -The 2022 surface temperature was 1.55 °F (0.86 °Celsius) warmer than the 20th-century average of 57.0 °F (13.9 °C) and 1.90 ˚F (1.06 ˚C) warmer than the pre-industrial period (1880-1900).
